Hi, We are getting 2 different field names for the same parameter from the source. messaging.message_payload_size_bytes comes in one trace, messaging.message.payload_size_bytes comes in another trace. The difference here is _ & . in these fields. We are using 0.55.0 version of the OTEL collector. Pls let me know whether this issue resolved ? Any other fields have the similar issue ? Few details about the versions: "key" : "telemetry.auto.version", "value" : { "stringValue" : "1.18.0" } }, { "key" : "telemetry.sdk.language", "value" : { "stringValue" : "java" } }, { "key" : "telemetry.sdk.name", "value" : { "stringValue" : "opentelemetry" } } "scope" : { "version" : "1.18.0-alpha", "name" : "io.opentelemetry.kafka-clients-0.11" } { "key" : "process.executable.path", "value" : { "stringValue" : "/usr/local/openjdk-11binjava" } }, { "key" : "process.pid", "value" : { "intValue" : "1" } }, { "key" : "process.runtime.description", "value" : { "stringValue" : "Oracle Corporation OpenJDK 64-Bit Server VM 11.0.12+7" } }, { "key" : "process.runtime.name", "value" : { "stringValue" : "OpenJDK Runtime Environment" } }, { "key" : "process.runtime.version", "value" : { "stringValue" : "11.0.12+7" } }
